IMPROVEMENT IN CAR-VENTILATORS AND DUST-DEFLECTORS.

Specification forming part of Letters Patent No. 180,844, dated August8, 1876; application filed May 16, 1876.

To all whom it may concern:

Be it known that I, AUGUSTUS B. OHILDS, of 16 Mark Lane, London,England, have invented a certain new and useful Improvement inOar-Ventilators-and Dust-Deflectors; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being bad to the accompanyingdrawings, in which Figure 1 is an elevation of a car-window with myimprovement applied thereto. Fig. 2 is a horizontal section of the same.Fig. 3 is a perspective view of the fixture detached.

My improvement relates to deflectors attached to the car on each side ofthe windows or doors, for the purpose of deflecting the current of airproduced by the motion of the car, thereby preventing the dust andcinders from entering the car.

The invention consists in the construction and arrangement of parts, ashereinafter more fully described.

A represents the side of a car, and B is one of the windows. 0 O are thedeflectors, arranged on opposite sides of the window, and extending alittle above and below the same. They are usually made about six incheswide, and are hung on pivots, so as to change their positionautomatically under the action of the wind. Under -motion they standbackward at an angle of about forty-five degrees, more or less, so thatall dust, cinders, &c., which strike them at the backward angle will bethrown off away from the windows or door,

as indicated by the arrows in Fig. 2, and will not enter the car.

When the motion of the car is reversed, the deflectors shiftautomatically upon their pivots to the opposite position by the pressureot' the wind, so that in running in either direction the deflectors willexclude the dust.

The deflectors may be made of wood or any other suitable material, or aframe may be used provided with glass, canvas, or wiregauze, and theymay be attached on each side of the doors or windows, or both.

To make these deflectors convenient in use, also to gage the angle towhich they adjust themselves, and, furthermore, to easily apply them tocars nowin use, some convenient fixtures must be used for pivoting thesame, so that they will turn easily. I prefer the follow ing: 1) D aremetallic edge-plates or shoes, attached fast by screws to the top andbottom edges of the deflectors. They are preferably made concave incross-section, so as to embrace the said edges, and thereby increase thestrength. At the inner ends they have pivots g g, which form the axesupon which the deflectors turn. E E are the bearings, which support thepivots g 9. These bearings are constructed with a flat leaf, h, which isscrewed to the wood-work, and also with beveled wings i i, which standin opposite directions at an angle of about forty-five degrees, more orless. In the center is the box k, in which the pivot rests. Theedge-plate D rests between the wings i i, and in the backward andforward motion of the deflector, in changing position, the plate Dstrikes the wings 'i '5, thereby gaging the position of the deflector.

The sides of the plates D D have, preferably, rubber packings p p, whichstrike the wings and prevent shock.

The devices above described are in convenient and simple form forattaching the deflectors to the cars. The bearings E have simply to bescrewed in place, and furnish their own stops to the deflector withoutallowing the latter to strike the wood, which it would soon mar and wearaway. The edgeplates D D obviate the same wear upon the deflector, and,furthermore, give strength to the latter by incasing their edges iniron.

I am aware that ventilating or deflecting wings have been used incar-windows; such I do not claim What I claim as new is- 1. The swingingself -adjusting deflectors O O, constructed with the metallicedge-plates D D, in combination with the bearings E E, provided with theangular wings or stops 0' i, as shown and described, and for the purposespecified.

2. The bearings E, constructed with the angular wings or stops 'i z, forgaging the throw of the deflectors in opposite directions, In witnesswhereof I have hereunto signed and with the boxes k, for receiving thepivots my name in the presence of two subscribing ot' the deflectors, asherein shown and (10- witnesses. scribed.

3. The metallic edge-plates D D, made con- AUGUSTUS BRYANT GHILDS. cave,to receive and hold the ends of the deflectors, and provided with thesolid pivots g g, Witnesses: as shown and described, and for the purposeGEO. MILLER, specified. JOHN GIRToN.
